Multi Purpose Thruline Wattmeter RF Power Analys
Information
The Model 4391 is a multi-purpose Radio Freouency
wattmeter designed around a microcomputer. A fairly
extensive program stored in permanent memory controls
the operation of the instrument at all times, permitting
the detection and correction of various error sources and
the refinement of the raw data produced by the directional
detectors. Thus, the instrument can compute VSWR,
amplitude modulation, and various decibel variables
reducing the odds of error and making such measurements
consistent or repeatable regardless of who is making the
measurement.
Other benefits include extended range using standard
elements in some modes of operation, continuous monitoring
monitoring of maximum and minimum readings, a peaking
aid, and error messages.
Because of its complexity, the proper use of the 4391
is not always obvious. For this reason it is strongly
advised that this manual be read in its entirety before
using the device.
